ENAMELED LETTER FOR SIGNS.

SPECIFICATION forming part of Letters Patent No. 273,024, dated February 27, 1883.

Application filed October 16, 1882. (No model.)

To all whom it may concern:

Be it known that I, JULIUS CAESAR, of the city, county, and State of New York, have invented certain new and useful Improvements in Enameled Letters for Signs, of which the following is a specification.

The well-known enameled letters and figures which are used for signs and other advertising purposes have the disadvantage that in cementing them to the glass or other surfaces the surface enamel is liable to crack by the pressure exerted on the metal body of the letter or figure when applying it to the glass or other surface, which requires the rebaking and re-enameling of the cracked portion of the letter or figure. Another point of disadvantage is, that the cement is irregularly spread along the edges at the rear side of the letter or figure, so as to present thus an unsightly appearance from theinside, especially when used on the glass panes of show-windows or doors.

In the accompanying drawings, Figure 1 represents a front elevation of my improved letter. Fig. 2 is a rear elevation; and Fig. 3, a horizontal section on line 00 m, Fig. 2.

Similar letters of reference indicate corresponding parts.

A in the drawings represents an improved letter or figure, which is stamped or cut of copper or other metal plate in the usual manner. The body of the letter or figure is next stamped up, by means of suitable dies, into convexo-concave form, and in such a manner that flat narrow portions or border-edge a are formed along the rear side. The letteror figure A is then covered with enamel, except the flat narrow portion a, and baked in the usual manner. The narrow portion a of the letter is left without enamel, as the cement will better hold to the metal, and by it moresecurely o fasten the letters to the backing on which they are to be placed. The convexo concave shape of the body imparts greater stiffness to the metal foundation, so as to resist the pressure exerted thereon and protect the enamel cov ering against cracking when cementing the letters or figures to the glass or other surface. In cementing the letters to the glass or other surface, the cement is quickly and uniformly spread by the spatula over the flat portions a a not covered by the enamel, and the letter or figure then placed in position and pressed against the glass or other surface to which it is to be applied. The narrow edge a, which is not enameled,is cemented to the backing, and will supportthe letter or figure in a very reliable manner,while detracting but little from the appearance of the letters when seen from the inside. tached with greater facility to the glass or other surface and are greatly improved in appearance by the plastic character imparted by their 'convexo-conca ve shape.

Having thusdescribed my invention, Iclaim as new and desire to secure by Letters Patent-- As a new article of manufacture, letters for signs made of sheet-metal plate stamped up into a convexo-concave body and enameled on both sides, with a narrow fiat portion, a, at its edge and on the rear side without enamel, substantially as and for the purpose set forth.

In testimony that I claim theforegoingas my invention I have signed my name in presence of two subscribing witnesses.
